The Massachusetts Department of Transportation is soliciting bids for the design‑build construction of the Belmont Community Path – Phase I, a shared‑use pedestrian and bicycle pathway that forms part of the Massachusetts Central‑Region Transportation (MCRT) Trail. The scope includes extensive earthwork, asphalt paving, retaining walls, bridge/culvert construction, utility relocation, lighting, drainage improvements, environmental mitigation, and compliance with a host of federal and state regulations (including endangered‑species and wetlands protections). The project budget is estimated at $35.864 million and will be executed over roughly three years, encompassing a one‑year pre‑construction phase, a seven‑day rail‑outage window, and a subsequent nine‑month post‑outage phase.
• Construct ~1.25 mi of off‑road, 12‑ft wide paved path with shoulders, retaining walls, and a grade‑separated under‑pass beneath active MBTA rail.
• Perform extensive utility coordination (water, sewer, gas, electric, telecom, MBTA rail) and satisfy stringent environmental requirements (wetlands, bat protection, sediment control).
• Provide civil‑engineering services (soil investigation, micropiles, temporary shoring, bridge erection) and adhere to high‑value insurance, labor‑participation, and Buy‑America mandates.
